Activity 9.2: Let us observe and create

1. Take a bowl or any container and fill it half with water.

3. Take a small piece of black or dark coloured thick paper and spread a few drops of the salt solution on it (Fig.a).
4. You can also create any art of your choice with this salt solution.
5. Allow it to dry and then observe it (Fig.b and Fig.c).

Question 1.

Do you observe some patches on the paper? What do you think is left on the paper? Class 6

Yes, as the water evaporates, it leaves behind the solid salt, which can be felt by touching the paper.
